| Abstract | The 12-month running means of methane (CH4) Concentrations at the surface/lower troposphere averaged for latitude groups 1-8 (1 82-63 degrees N; 2, 56-53 degrees N; 3, 47-36 degrees N; 4, 32-26 degrees N; 5, 20-13 degrees N; 6, 5-14 degrees S, 7, 41 degrees S only; 8, 65-90 degrees S) showed oscillations but the peak spacings were similar to that of 30 mb wind (similar to 30 months) only for groups 3, 4 and 7. A cross-correlation with 30 mb wind showed maximum good correlations ( 0.7) with a phase lag of about 6 months for CH4 in group 7 (in agreement with Camp et al. [2001. The sensitivity of tropospheric CH4 to the interannual variability in stratospheric ozone. Chemosphere-Global Change Science 3, 147-156]) and about 12 months for CH4 in groups 6 ( 0.7). A spectral analysis indicated for 30 mb wind, a prominent Quasi-biennial oscillation (QBO) at 2.34 years and a minor peak at 2.06 years. For Southern Oscillation Index (SOI) (T-D), there was a prominent Quasi-triennial oscillation (QTO) peak at 3.6 years, but there was also a less prominent but significant QBO at 2.54 years. All CH4 groups showed significant QBOs in the range 2.22-2.58 years but also showed more prominent QTOs in the range 3.2-4.1 years, and barely significant peaks in the range 1.6-1.9 years (19-22 months). To test the ozone mechanism proposed by Hamilton and Fan [2000. Effects of the stratospheric QBO on long-lived greenhouse gases in the troposphere. Journal of Geophysical Research 105, 20581-20587] (stratospheric wind QBO affecting stratospheric ozone, in turn affecting the filtered UV, the tropospheric OH radical, and finally tropospheric CH4), TOMS-SBUV data were analyzed. Many CH4 and ozone groups showed QBOs in the range 2.22-2.77 years, and lower periodicities in the range 1.60-1.91 years (19-22 months [Tung, K.K., Yang, H., 1994. Global QBO in circulation and ozone. Part I. Reexamination of observational evidence. Journal of Atmospheric Science 51, 2699-2707]), confirming that the ozone mechanism was operative. A disconcerting feature is the QTO of similar to 3.5 years.. which was present in CH4 in all latitude groups, but in ozone, only in groups 3, 6, 7. |
